Phytochemical content or natural products can be defined as a heterogeneous group of natural metabolic products that are not essential for the vegetative growth of producing organisms, but are considered as differentiation compounds that provide adaptive roles. The most commonly known phytochemical content is divided into several compounds such as alkaloids, falfonoids, steroids, terpenoids, sapinin, tannins, and phenols. This study aims to identify the phytochemical compounds present in several types of medicinal plants.

information, especially about the types of plants that exist in the Lambusango
Wildlife Reserve area on Buton Island. This research uses literature study
method. From the research results, there are about 110 species of plants that
have been collected, 104 species of which have known potential utilization by
the local community. There were 10 plant species in bush vegetation, 10 plant
species in secondary forest, and 21 plant species in primary forest.
Furthermore, 21 species of seed plants (Spermatophyta), 21st species of ferns
(Pteridophyta) and 16 species of mosses (Pteridophyta) were obtained

The purpose of this study was to determine the types of seagrasses in the intertidal zone of Lakeba Beach, Baubau City. The type of research used is qualitative research with the method used being a direct survey to a location with a transect of 200 meters and a width of 50 meters and conducting interviews with two respondents. The results found on the lakeba beach consisted of 2 orders, 2 families, and 5 seagrass species. Order Helobiae and Alismatales, family Hydrocharitaceae and Cymodoceae. Furthermore, the species found were Enhalus acoroides, Halophylaovalis, Halodule uninervis, Halophyla spinolosa, and Cymodocea rotundata.

Lakeba Beach in Sulaa Village, Baubau City, Southeast Sulawesi Regency is the presence of a beach in the west which has a marine ecosystem/seacoast environment, the waters of the Sula village on the coast of Lakeba have a sloping topography and a suitable substrate as a place to live for a diversity of marine animals, one of which is species of marine animals. molluscs, the purpose of this study was to determine the types of mollusks and the morphological classification of molluscs on the lakeba coast, Baubau city.

This type of research is exploratory to collect mollusk species in the intertidal zone with a field observation approach. The location of this research is at Lakeba beach, Baubau City and was carried out from 20 August 2022. The object studied in this study is the identification of mollusc species, The method used is line transect with zigzag method. Analytical technique.

The results showed that the types of molluscs found were molluscs in the gastropod group such as moon eye snail, oliva reticulata, hexaplex trunculus, lola and abalone. Molluscs are one of the macrozoobenthos groups that have soft bodies and mostly secrete calcium carbonate which forms a hard shell of chitin substance that functions in self-protection. (Candri et al., 2020)The ecosystem owned by this type of mollusk has decreased in number, because it is used as a food source by the surrounding community. In addition, Lakeba beach in Baubau City is also a tourist spot and is close to residential areas so as to reduce the amount of mollusk diversity. So this research is important to do.
